推荐答案

他想要接收数据来自宽带。我会假设它是一些端口。但无论如何，我猜是USB。 USB不能是COM1。所以基本上他不知道打开哪个端口。程序很好。所有OP需要做的是找出调制解调器或设备连接到哪个端口，并用端口号替换COM1。

He wants to receive data from "broadband". I will assume that it is some port. But in any case it is USB I guess. USB can not be COM1. So basically he does not know which port to open. Program is fine. All OP needs to do is find out which port the modem or the device is connected to and replace COM1 with the port number of that.
